The story is pretty decent....but the things that the author makes the Side Character (male) more important and more screen time than the Main Character is a pretty stupid move.
First, the art in this is very good. However, the plot is very bad and the ending is even worse.
There is a douche in the story who keeps harassing the FMC in the first half of the story. After that, FMC's mother who is a hot milf is introduced and the douche goes after her. Not only that, he ends up getting the milf as well just cause he gave her a sob story about how he himself was cucked when he was in high school. The author tries really hard to make the douche a good guy and even retcons the milf's husband, just to make her and the douche end up together. At the end, the douche becomes the stepdad of the FMC who he'd been harassing earlier.
Overall, art is good, so you can read it just for that if you want.
